phpinfo

(PHP 4, PHP 5)

phpinfo — Outputs lots of PHP information

Описание

bool phpinfo ([ int $what = INFO_ALL ] )

Outputs a large amount of information about the current state of PHP. This includes information about PHP compilation options and extensions, the PHP version, server information and environment (if compiled as a module), the PHP environment, OS version information, paths, master and local values of configuration options, HTTP headers, and the PHP License.

Because every system is setup differently, phpinfo() is commonly used to check configuration settings and for available predefined variables on a given system.

phpinfo() is also a valuable debugging tool as it contains all EGPCS (Environment, GET, POST, Cookie, Server) data.

Параметри

what

The output may be customized by passing one or more of the following constants bitwise values summed together in the optional what parameter. One can also combine the respective constants or bitwise values together with the or operator.

**phpinfo()** options
Name (constant)	Value	Description
INFO_GENERAL	1	The configuration line, `php.ini` location, build date, Web Server, System and more.
INFO_CREDITS	2	PHP Credits. See also phpcredits().
INFO_CONFIGURATION	4	Current Local and Master values for PHP directives. See also ini_get().
INFO_MODULES	8	Loaded modules and their respective settings. See also get_loaded_extensions().
INFO_ENVIRONMENT	16	Environment Variable information that's also available in `$_ENV`.
INFO_VARIABLES	32	Shows all predefined variables from EGPCS (Environment, GET, POST, Cookie, Server).
INFO_LICENSE	64	PHP License information. See also the » license FAQ.
INFO_ALL	-1	Shows all of the above. This is the default value.

I wanted a simple *function* to convert the output of phpinfo into an array.  Here's what I came up with thanks to alot of the previous authors tips, and the source file: php-5.2.6/ext/standard/info.c



Call this function like phpinfo_array() prints the array, phpinfo_array(1) returns the array for your own processing.



== Sample Output ==

[PHP Configuration] => Array

 (

  [PHP Version] => 5.2.6

  [PHP Egg] => PHPE9568F34-D428-11d2-A769-00AA001ACF42

  [System] => Linux askapache 2.6.22.19-grsec3

  [Build Date] => Nov 11 2008 13:09:07

  [Configure Command] =>  ./configure --prefix=/home/grsec/bin/php 

  [Server API] => FastCGI



  [IPv6 Support] => enabled

 [Zend Egg] => PHPE9568F35-D428-11d2-A769-00AA001ACF42

  [PHP Credits Egg] => PHPB8B5F2A0-3C92-11d3-A3A9-4C7B08C10000

 )



[mbstring] => Array

 (

  [mbstring.http_input] => pass

  [mbstring.internal_encoding] => Array

    (

     [0] => ISO-8859-1

     [1] => no value

    )



  [mbstring.language] => neutral

   )



[mcrypt] => Array

 (

  [Version] => 3.5.7

  [Api No] => 20031217

 )



<?php

function phpinfo_array($return=false){

 /* Andale!  Andale!  Yee-Hah! */

 ob_start(); 

 phpinfo(-1);

 

 $pi = preg_replace(

 array('#^.*<body>(.*)</body>.*$#ms', '#<h2>PHP License</h2>.*$#ms',

 '#<h1>Configuration</h1>#',  "#\r?\n#", "#</(h1|h2|h3|tr)>#", '# +<#',

  "\n".'<tr><td>PHP Egg</td><td>$1</td></tr>',

  '<tr><td>PHP Credits Egg</td><td>$1</td></tr>',

  '<tr><td>Zend Engine</td><td>$2</td></tr>' . "\n" .

  '<tr><td>Zend Egg</td><td>$1</td></tr>', ' ', '%S%', '%E%'),

 ob_get_clean());



 $sections = explode('<h2>', strip_tags($pi, '<h2><th><td>'));

 unset($sections[0]);



 $pi = array();

 foreach($sections as $section){

   $n = substr($section, 0, strpos($section, '</h2>'));

   preg_match_all(

   '#%S%(?:<td>(.*?)</td>)?(?:<td>(.*?)</td>)?(?:<td>(.*?)</td>)?%E%#',

     $section, $askapache, PREG_SET_ORDER);

   foreach($askapache as $m)

       $pi[$n][$m[1]]=(!isset($m[3])||$m[2]==$m[3])?$m[2]:array_slice($m,2);

 }



 return ($return === false) ? print_r($pi) : $pi;

}

A simple method to style your own phpinfo() output.



<style type="text/css">

#phpinfo {}

#phpinfo pre {}

#phpinfo a:link {}

#phpinfo a:hover {}

#phpinfo table {}

#phpinfo .center {}

#phpinfo .center table {}

#phpinfo .center th {}

#phpinfo td, th {}

#phpinfo h1 {}

#phpinfo h2 {}

#phpinfo .p {}

#phpinfo .e {}

#phpinfo .h {}

#phpinfo .v {}

#phpinfo .vr {}

#phpinfo img {}

#phpinfo hr {}

</style>



<div id="phpinfo">

<?php



ob_start () ;

phpinfo () ;

$pinfo = ob_get_contents () ;

ob_end_clean () ;



// the name attribute "module_Zend Optimizer" of an anker-tag is not xhtml valide, so replace it with "module_Zend_Optimizer"

echo ( str_replace ( "module_Zend Optimizer", "module_Zend_Optimizer", preg_replace ( '%^.*<body>(.*)</body>.*$%ms', '$1', $pinfo ) ) ) ;



?>

</div>

My hosting company doesn't let me edit my php.ini file, but I wanted most of the same values, so I adapted one of the above posts to let me convert the information from phpinfo into a page where so can just copy and paste the info into a new php.ini file.



<?php

ob_start();

phpinfo(INFO_CONFIGURATION);

$phpinfo = array('phpinfo' => array());

if(preg_match_all('#(?:<h2>(?:<a name=".*?">)?(.*?)(?:</a>)?</h2>)|(?:<tr(?: class=".*?")?><t[hd](?: class=".*?")?>(.*?)\s*</t[hd]>(?:<t[hd](?: class=".*?")?>(.*?)\s*</t[hd]>(?:<t[hd](?: class=".*?")?>(.*?)\s*</t[hd]>)?)?</tr>)#s', ob_get_clean(), $matches, PREG_SET_ORDER))

    foreach($matches as $match)

        if(strlen($match[1]))

            $phpinfo[$match[1]] = array();

        elseif(isset($match[3]))

            $phpinfo[end(array_keys($phpinfo))][$match[2]] = isset($match[4]) ? array($match[3], $match[4]) : $match[3];

        else

            $phpinfo[end(array_keys($phpinfo))][] = $match[2];

?>



<?php

    foreach($phpinfo as $name => $section) {

         foreach($section as $key => $val) {

            if(is_array($val))

                echo "$key = $val[0]<br>";

            elseif(is_string($key))

                echo "$key = $val<br>";

            else

                echo "$val<br>";

        }

        echo "\n";

    }

?>

To extract all of the data from phpinfo into a nested array:

<?php

ob_start();

phpinfo();

$phpinfo = array('phpinfo' => array());

if(preg_match_all('#(?:<h2>(?:<a name=".*?">)?(.*?)(?:</a>)?</h2>)|(?:<tr(?: class=".*?")?><t[hd](?: class=".*?")?>(.*?)\s*</t[hd]>(?:<t[hd](?: class=".*?")?>(.*?)\s*</t[hd]>(?:<t[hd](?: class=".*?")?>(.*?)\s*</t[hd]>)?)?</tr>)#s', ob_get_clean(), $matches, PREG_SET_ORDER))

    foreach($matches as $match)

        if(strlen($match[1]))

            $phpinfo[$match[1]] = array();

        elseif(isset($match[3]))

            $phpinfo[end(array_keys($phpinfo))][$match[2]] = isset($match[4]) ? array($match[3], $match[4]) : $match[3];

        else

            $phpinfo[end(array_keys($phpinfo))][] = $match[2];

?>



Some examples of using individual values from the array:



<?php

    echo "System: {$phpinfo['phpinfo']['System']}<br />\n";

    echo "Safe Mode: {$phpinfo['PHP Core']['safe_mode'][0]}<br />\n";

    echo "License: {$phpinfo['PHP License'][0]}<br />\n";

?>



To display everything:



<?php

    foreach($phpinfo as $name => $section) {

        echo "<h3>$name</h3>\n<table>\n";

        foreach($section as $key => $val) {

            if(is_array($val))

                echo "<tr><td>$key</td><td>$val[0]</td><td>$val[1]</td></tr>\n";

            elseif(is_string($key))

                echo "<tr><td>$key</td><td>$val</td></tr>\n";

            else

                echo "<tr><td>$val</td></tr>\n";

        }

        echo "</table>\n";

    }

?>



Note: In order to properly retrieve all of the data, the regular expression matches table headers as well as table data, resulting in 'Local Value' and 'Global Value' showing up as 'Directive' entries.

big thanx 2 Mardy dot Hutchinson at gmail dot com

very good!



some fixes to correct result displaying:

1. we need to trim $matches [1], 'cause there can be empty lines;

2. not bad to remove <body> tag 'cause styles for it not apply correctly...

3. ...and change styles a little (remove "body" selector)



we need to change two lines:



<?php

preg_match ('%<style type="text/css">(.*?)</style>.*?(<body>.*</body>)%s', ob_get_clean(), $matches);

?>

to

<?php

preg_match ('%<style type="text/css">(.*?)</style>.*?<body>(.*?)</body>%s', ob_get_clean(), $matches);

?>



and



<?php

preg_split( '/\n/', $matches[1] )

?>

to

<?php

preg_split( '/\n/', trim(preg_replace( "/\nbody/", "\n", $matches[1])) )

?>



That's all! Now we have a really flexible addition to phpinfo();

Embedding phpinfo within your page, that already has style information:



The phpinfo output is wrapped within a <div class='phpinfodisplay'>, and we privatize all the style selectors that phpinfo() creates.



Yes, we cheat on preparing the selector list.



<?php

ob_start();

phpinfo();



preg_match ('%<style type="text/css">(.*?)</style>.*?(<body>.*</body>)%s', ob_get_clean(), $matches);



# $matches [1]; # Style information

# $matches [2]; # Body information



echo "<div class='phpinfodisplay'><style type='text/css'>\n",

    join( "\n",

        array_map(

            create_function(

                '$i',

                'return ".phpinfodisplay " . preg_replace( "/,/", ",.phpinfodisplay ", $i );'

                ),

            preg_split( '/\n/', $matches[1] )

            )

        ),

    "</style>\n",

    $matches[2],

    "\n</div>\n";

?>



Perhaps one day the phpinfo() function will be modified to output such a safe string on its own.

One note on the above functions for cleaning up the phpinfo() HTML and throwing it into an array data structure. In order to catch all of the info tidbits the preg_match_all has to be tweaked to deal with 2 and 3 column tables.





I have changed the preg_match_all() here so that the last <td></td> is optional





<?php


function parsePHPConfig() {


    ob_start();


    phpinfo(-1);


    $s = ob_get_contents();


    ob_end_clean();


    $a = $mtc = array();


    if (preg_match_all('/<tr><td class="e">(.*?)<\/td><td class="v">(.*?)<\/td>(:?<td class="v">(.*?)<\/td>)?<\/tr>/',$s,$mtc,PREG_SET_ORDER))


        foreach($mtc as $v){


            if($v[2] == '<i>no value</i>') continue;


            $a[$v[1]] = $v[2];


        }


    }


    return $a;


}


?>

Here's a variant of "print it without headers, but include the style information":



<?php

ob_start();

phpinfo();

$info = ob_get_clean ();



$matches = array ();

$i = preg_match ('%(<style type="text/css">.*</style>).*<body>(.*)</body>%s', $info, $matches);



print $matches [1]; # Style information

print $matches [2]; # Body

<?php


function parsePHPConfig() {


    ob_start();


    phpinfo(INFO_CONFIGURATION);


    $s = ob_get_contents();


    ob_end_clean();


    $a = $mtc = array();


    if (preg_match_all('/<tr><td class="e">(.*?)<\/td><td class="v">(.*?)<\/td><td class="v">(.*?)<\/td><\/tr>/',$s,$mtc,PREG_SET_ORDER)) {


        foreach($mtc as $v){


            if($v[2] == '<i>no value</i>') continue;


            $a[$v[1]] = $v[2];


        }


    }


    return $a;


}

This is a slight modification to the previous code by "code at adspeed dot com" that extracts the PHP modules as an array. I used it on PHP 4.1.2 and it failed as the <h2> tags also had an align="center". So this update changes the regex for those tags:



<?php



/* parse php modules from phpinfo */



function parsePHPModules() {

 ob_start();

 phpinfo(INFO_MODULES);

 $s = ob_get_contents();

 ob_end_clean();



 $s = strip_tags($s,'<h2><th><td>');

 $s = preg_replace('/<th[^>]*>([^<]+)<\/th>/',"<info>\\1</info>",$s);

 $s = preg_replace('/<td[^>]*>([^<]+)<\/td>/',"<info>\\1</info>",$s);

 $vTmp = preg_split('/(<h2[^>]*>[^<]+<\/h2>)/',$s,-1,PREG_SPLIT_DELIM_CAPTURE);

 $vModules = array();

 for ($i=1;$i<count($vTmp);$i++) {

  if (preg_match('/<h2[^>]*>([^<]+)<\/h2>/',$vTmp[$i],$vMat)) {

   $vName = trim($vMat[1]);

   $vTmp2 = explode("\n",$vTmp[$i+1]);

   foreach ($vTmp2 AS $vOne) {

   $vPat = '<info>([^<]+)<\/info>';

   $vPat3 = "/$vPat\s*$vPat\s*$vPat/";

   $vPat2 = "/$vPat\s*$vPat/";

   if (preg_match($vPat3,$vOne,$vMat)) { // 3cols

     $vModules[$vName][trim($vMat[1])] = array(trim($vMat[2]),trim($vMat[3]));

   } elseif (preg_match($vPat2,$vOne,$vMat)) { // 2cols

     $vModules[$vName][trim($vMat[1])] = trim($vMat[2]);

   }

   }

  }

 }

 return $vModules;

}

?>

To obtain a phpinfo without headers (and css) :





<?php


ob_start();                                                                                                        


phpinfo();                                                                                                         


$info = ob_get_contents();                                                                                         


ob_end_clean();                                                                                                    





$info = preg_replace('%^.*<body>(.*)</body>.*$%ms', '$1', $info);


?>





You can then style your tables & headings :)

This function parses the phpinfo output to get details about a PHP module. 





<?php


/** parse php modules from phpinfo */


function parsePHPModules() {


 ob_start();


 phpinfo(INFO_MODULES);


 $s = ob_get_contents();


 ob_end_clean();


 


 $s = strip_tags($s,'<h2><th><td>');


 $s = preg_replace('/<th[^>]*>([^<]+)<\/th>/',"<info>\\1</info>",$s);


 $s = preg_replace('/<td[^>]*>([^<]+)<\/td>/',"<info>\\1</info>",$s);


 $vTmp = preg_split('/(<h2>[^<]+<\/h2>)/',$s,-1,PREG_SPLIT_DELIM_CAPTURE);


 $vModules = array();


 for ($i=1;$i<count($vTmp);$i++) {


  if (preg_match('/<h2>([^<]+)<\/h2>/',$vTmp[$i],$vMat)) {


   $vName = trim($vMat[1]);


   $vTmp2 = explode("\n",$vTmp[$i+1]);


   foreach ($vTmp2 AS $vOne) {


    $vPat = '<info>([^<]+)<\/info>';


    $vPat3 = "/$vPat\s*$vPat\s*$vPat/";


    $vPat2 = "/$vPat\s*$vPat/";


    if (preg_match($vPat3,$vOne,$vMat)) { // 3cols


     $vModules[$vName][trim($vMat[1])] = array(trim($vMat[2]),trim($vMat[3])); 


    } elseif (preg_match($vPat2,$vOne,$vMat)) { // 2cols


     $vModules[$vName][trim($vMat[1])] = trim($vMat[2]); 


    } 


   } 


  } 


 } 


 return $vModules;


}


?>





Sample Output:


[gd] => Array


(


  [GD Support] => enabled


  [GD Version] => bundled (2.0.28 compatible)


  [FreeType Support] => enabled


  [FreeType Linkage] => with freetype


  [FreeType Version] => 2.1.9


  [T1Lib Support] => enabled


  [GIF Read Support] => enabled


  [GIF Create Support] => enabled


  [JPG Support] => enabled


  [PNG Support] => enabled


  [WBMP Support] => enabled


  [XBM Support] => enabled


)





[date] => Array (


  [date/time support] => enabled


  [Timezone Database Version] => 2005.14


  [Timezone Database] => internal


  [Default timezone] => America/Los_Angeles


  [Directive] => Array (


     [0] => Local Value


     [1] => Master Value


  )


  [date.timezone] => Array (


     [0] => no value


     [1] => no value


  )


 )








<?php


/** get a module setting */


function getModuleSetting($pModuleName,$pSetting) {


 $vModules = parsePHPModules();


 return $vModules[$pModuleName][$pSetting];


}


?>





Example: getModuleSetting('gd','GD Version'); returns "bundled (2.0.28 compatible)"
